Analysis based on 6 articles · First reported Jul 21, 2026 · Last updated Jul 21, 2026
The project's delays could slow South Korea's semiconductor expansion, affecting global chip supply. Local opposition may increase costs and timeline uncertainty for Samsung Electronics and SK Hynix.
South Korea plans to build the Honam semiconductor industrial complex in its southwest by 2030, costing at least 800 trillion won ($540 billion). The project, central to President Lee Jae Myung's strategy to spread AI chip benefits beyond Seoul, faces local opposition over power and water needs. Power demand from four planned fabs could equal 70-80% of regional electricity consumption. Residents oppose new transmission lines and nuclear reactors, and demand consultation on raising Dongbok Dam for water supply. Energy Minister Kim Sung-hwan may consider new nuclear reactors. Similar projects in South Korea — Yongin have faced delays due to infrastructure issues.
